Unless specified otherwise,
the distribution parameters are calculated as:
pk=wk/S for k=0,…,n−1,
in which the values wk,
commonly known as the weights, shall be non-negative, non-NaN, and non-infinity.

The n+1 distribution parameters bi,
also known as this distribution's interval boundaries, shall satisfy the relation bi<bi+1 for i=0,…,n−1.

Unless specified otherwise,
the remaining n+1 distribution parameters are calculated as
ρk=wk/S for k=0,…,n, in which the values wk,
commonly known as the weights at boundaries, shall be non-negative, non-NaN, and non-infinity.
